High-speed DC circuit-breakers
for Rolling Stock
Type UR6, UR10 & UR15
General information
UR6, UR10 and UR15 are DC high-speed current limiting
circuit-breakers with natural cooling, trip free, single pole,
bi-directional, with electromagnetic blow-out, electric control
circuits and direct over-current instantaneous release.
Of open type construction, the UR6, UR10 and UR15 can
also be delivered with protective enclosure IP55 for roof or
under-frame mounting on traction vehicles.
These circuit-breakers are primarily designed to protect
main and auxiliary circuits of DC traction vehicles against
short-circuits and overload currents, as well as to connect
or isolate these circuits to and from the vehicles power
supply.
Selecting the right product for your vehicles requires careful
consideration and computing from Sécheron, for the
application load cycle, the environmental temperature and
high-voltage cable or busbar section.
Applications
• Protection of electric traction and auxiliary circuits on Metro, EMU and LRV vehicles

Non cumulative overloads at Tamb=+40°C, starting from breaker’s cold state, and with high voltage connection size as per (1).
The values are based on trip setting range 1.2 - 2.4 kA for UR6, 1.5 - 3.2 kA for UR10 and 1.8 - 3.6 kA for UR15. May the selected trip setting range be different, maximum values of the overload capacity should
match the maximum value of the selected tripping range.

Required informations for breaker selection
In order to select the appropriate breaker suited to your application, the following informations must be provided to Sécheron.
Once these data computed, and in function of the maximum allowed temperature rise of the critical parts of the different breakers
UR6/10/15, Sécheron will recommend the breaker type that matches your application.
The following data and informations must be sent to Sécheron for computing.
1 - Application load cycle
An excel table with the load cycles the breaker will have to withstand in the application, shall be sent to Sécheron for computing, and shall include as a minimum the following informations:
• The peak value Ip3 and the i² x t of the most energetical load of the vehicle’s trip
• The highest peak value Ip1 of the vehicle’s trip and its duration
• The Irms current (Root Means Square) of the vehicle’s trip

Note: It is recommended that the current density of the high voltage connections wired to the DC circuit-breaker and related to the rms
current of the application shall not exceed 1.7 ~ 2.0 A/mm².
For current density that exceeds the recommended value, the breaker thermal current may have to be derated in function of the
application.

ECO-Drive integrated control module
Légende
Légende
The ECO-Drive is a small control module directly integrated on the UR6, UR10 and UR15 breaker, for both stand-alone version
or when delivered with protective enclosure, for configuration with electric holding and 2 auxiliary switches. The ECO-Drive
is installed on the UR breaker’s closing device and manages the closing - holding sequences once it receives a closing order
from the vehicle.
Additional weight with
this option is 0.6 kg.

Space needed for the removal of the auxiliary housing
This option offers many advantages to the system integrators including the following features:
• UR6/10/15 breakers do not need additional hardware anymore to manage the closing - holding sequence
• Reduction of the overall space necessary to operate the circuit-breaker
• Reduction of overall installation costs of the DC circuit-breaker
• Reduction of holding power consumption and operational costs versus conventional holding variant
• Reduction of the risks of damaging the closing coil during commissioning and service operations
The UR breaker together with the ECO-Drive is fully compliant for electromagnetic compatibility with EN 50121-3-2 and with
EN 50155: § 5.1.1.2 short (10 ms) interruptions class S2 and § 5.1.3: voltage dips / variation (at 0.6Un during 100ms) class C1.
